How to call Google Map on Laravel view.blade

I am trying to use google map on the page but facing some trouble. I used this api, and installed it without a problem. I set the controller and route as below.

public function map()
{
    $response = \GoogleMaps::load('geocoding')
        ->setParam(['address' => 'tokyo'])
        ->get();

    return view('welcome', compact('response'));
}

Route::get('/', 'PagesController@map');

and calling the API into view.blade. I used just this:

Do I need to add some script too? Becouse I am getting this error;

{ "error_message" : "This API project is not authorized to use this API.", "results" : [], "status" : "REQUEST_DENIED" }

or this error;

/maps/api/place/add/json?key=AIzaSyDRA160KmwA5Z-7KZn_JfJRdSNkkSiqKRB was not found on this server. That’s all we know.

What is the problem here? I double checked the API key. No problem with that. Already gave permission for my domain address too? What am I missing here?
